Okay, fair enough.

Stepping back, RTNL itself seems like the proper generic interface.
Would you agree?  At first, it seemed overkill to pack the information
into message buffers just to have the rest of RTNL unpack them, which
is why I mis-did what I did.  I think you've make it clear that that
overhead is worth the reuse.  Would that be more palatable?

Thanks!
